Abstract

Matching average degree of consolidation is a common approach to convert unit cell solutions for vertical drains to two and three-dimensional calculations. These techniques facilitate efficient computation and have been shown to accurately model settlement of the system. However, pore pressures are usually measured at the location of maximum pore pressure. This article demonstrates that use of permeability matching techniques theoretically results in different maximum pore pressures than in unit cells. Some guidance for the magnitude of the difference is provided as a rule of thumb to assist analysts judge the accuracy of their modelling compared with pore pressure measurements.
